Six British soldiers killed in Afghanistan, including one from east London who died when an Afghan policeman turned his gun on them and three others, are to be returned to Britain.

Warrant Officer Class 1 Darren Chant, 40, and four others were shot dead by a “rogue” Afghan police officer at a secure checkpoint in Nad-e-Ali in Helmand Province on November 3 in an attack claimed by the Taliban.

Victim: Grenadier Guardsman Sgt Matthew Telford and his wife, Kerry

As Regimental Sergeant Major, WO1 Chant, who was born in Walthamstow, was the top non-commissioned officer in the 1st Battalion the Grenadier Guards.

On the day he was killed he was due to be told he had been awarded a commission as an officer. He left his pregnant widow, Nausheen Chant, and three children from a previous marriage, Connor, 16, Adam, 10, and Victoria, eight.

Two days later Serjeant Phillip Scott, 30, of 3rd Battalion The Rifles, was killed by an improvised explosive device near Sangin in Helmand. The soldiers’ bodies will be flown into RAF Lyneham in Wiltshire.

After a private repatriation ceremony for their families, hearses carrying their Union flag-draped coffins will pass along the high street of nearby Wootton Bassett.

Crowds have appeared along the route to pay their respects since the bodies of British service personnel began being brought home through RAF Lyneham in 2007.

The procession will then continue to Oxford’s John Radcliffe Hospital.
